Specification of Letters Patent. Patented; 1 2, 1919.

Application filed September 24, 1917. Serial No. 194,299.

To all whom it may concern:

7 Be it known that 1, WILLIAM L. WHITE, a citizen of the United States, residing at Birmingham, in the county of Jeiferson and State of Alabama, have invented certain new and useful Improvements in Type-Writers, of which the following is a speci cation.

This invention'relates to improvements in and has for its object to provide an improved column selector and,

more particularly, one controlled from the Another object of the invention isto provide means whereby any column on a typewriter in a tabulated form may beinstantly selected. 1

With the I haveinvented the device illustrated in the accompanying drawings in which,

Figure 1 is a typewriter embracmg my nvention, certain parts essential to the Invention being removed; 7

Fig. 2 is a side elevational view of the machine; 7 I

Fig. 3 is a detail elevationalview of a typewriter carriage stopping mechanism;

Fig. 4 is a detail plan view of; acolumn' selecting means;

Fig. 51s an enlarged detail end, view of a portion of the mechanism;

Fig. 6 is a 5; and V Fig. 7 is a detail view of one of the dials and the pointer associated therewith.

Like reference characters indicate like, parts throughout the following specification and in the several views of thedrawings-in which 1 indicates a typewriter frame having a series of dials 2, 3,4, 5 and 6 positioned at the front of said frame, said dials embracing figures from 1 to 75 conforming to the plate 7 of the typewriter, each dial having fifteen numberspthereon. These dials are read in connection with fixed indicator pointers 8 and are formed on fixed to 11, 12, 13, and 14, which extend horizontally to the rear portion of the frame and have mounted thereon gears, of which 15, 16' and 19, mounted on shafts 10, 11 and 14, respectively, are shown, meshing with gearsfixed to shafts 25, 26, 27 28 and 29, rotating at right angles to the shafts 10 to 14. Of the last-mentioned gears, only above and other. objects in view,

front elevational view of a front elevational view of the 20, 21. and 24 meshing, respectively with 7 gears 15,16 and19 are shown. On the upper ends of shafts 25, 26,27, 28 and 29 are fixed other gears 30,31, 32, 33 and 34, which operate gears 35,36, 37,38 and 39, fixed on the short shafts 40, 41, 42, 43, 44,,respectively. These latter shafts carry pinions45, 46, 47, 48. and 49 meshing with theracks50, 51, 52, 53 and 54 on the column selector b ars or stops 55,56, 57, 5,8 and 59, which are slidable in grooves 60, 61, 62, 63 'and64 in the plate 65 mounted on the rearportion of said frame. A plate 66 is mounted on the carriage 67 of the typewriter and is provided with a series of spring controlled pins 68, 69, 70, 71 and 72,which are held normally away from-the plate 65. Pivotally mounted in vertical alinementwith one another are a series of bars 73, 74, 75, 76 and 77, which are operated by means of bell c'rank levers 78, 79, 80, 81 and 82, whe reby said plates 73 to 7 7 may be pressed against pins 68 to 72 to drive them against their spring tensions into the grooves 60 to. 64 inorder that when one of the tabulating keys 83, 84, 85, 86, and 87 is pressed, operating the vertical links,

88, 89, 90, 91 and 92, one of'said 68 to until said pin engages one of said column selecting bars 55 to ,59, thus stoppingv the carriage. By means of the ab'ovedescribed arrangement the carriage may be instantly brought to the column it is desired to select and this selection maybe made from the front of the machine by meansv of the in dicator hands on the dials 2 to. 6.

It will be seen that'each of the spring controlled pins 68 to 72,inclusive, when depressed, determine the sections of fifteen units within which the carriage is to be stopped, and the column-selector bars 55 to '59, inclusive, determine at what unit position, in each range of fifteen, the stopping will occur. Therefore, the spring-cone trolled pins 68 to 72, inclusive, may be termed tabulato-r stops; keys 83 to 87, inclusive, tabulator keys; and column-selector bars or stops 55 to 59, inclusive, denominational stops. 7 p

Inasmuch as the column-selecting bars or stops are liable to be moved when struck by a tabulating pin on the moving carriage, it is desirable to make definite provision for preventing such movement, rather than to depend upon the frictional resistance against movement of the bars in their grooves and upon the frictional resistance of the gearing through which said bars are positioned, Such provision is obtained by mounting set screws 2*, 3, r, 5, and 6 in the frame of the machme so that they can be turned to clamp, against improper movement, the shafts, carrying the milled heads 9, and thereby prevent improper displacement of said column-selecting bars 55 to 59, inclusive.

When it is desired to set a columirselecting bar to correspond with a certain indica' tion on the space plate 7, the milled head, having on its face an indication corresponding to the one selected on the space plate, is turned until the indication lies under the fixed pointer associated with said milled head. Then, upon depression of the proper scope of the invention, and portions of the improvements may be used without others.

Having thus described my invention, that which is claimed as new and desired to be secured by Letters Patent is:

1. In atypewriting machine, the combination with a traveling carriage, of columnselecting means including stops mounted at the rear of the machine, each adjustable transversely of the machine, means for severally setting said stops in adjusted position, said setting means including devices through which actuation of said setting means is effected, positioned at the front of the machine and having thereon scales numbered to conform with the numbering on the space scale of the machine, and indicators associated with said scales, whereby the positions of said stops relative to the space scale will be indicated, and means on said carriage for engaging with said stops.

2. In a typewriting machine, the combination with a traveling carriage, of columnselecting means therefor comprising stopmounted at the rear of the machine an d settable along a line parallel to the path of movementof said carriage, means for setting said stop at a desired position along said path of movement, and means, mounted at the front of the machine and associated von conforming to the figures on said space scale, and an indicator associated therewith.

3. In a typewriting machine, the combination with a traveling carriage, of a series of stops therefor, and means for moving each of said stops transversely of the machine, said stop-moving means including actuating members mounted at the front of the machine and having associated therewith dialsand indicators to show the positions of said stops, said dials having figures thereon conforming to the figures on the space scale of said machine.

it. In a typewriting machine," the combination with a traveling carriage, of a. series of stopping devices therefor, means for severally setting said stopping-devices, tabu-lator keys, and tabulatorkey-actuated means, connected to said carriage to move therewith, for determining which of said stopping devices shall be rendered effective.

5. In a-typewriting machine, the combinationW-ith-a carriage, of a column-selector including aseries of stops severally adjustable along limited ranges to correspond to certain positions on'the space scale of the machine, means for adjustably setting said stops, a second series of stops, and means including keys to severally place the stops of said second series in position to engage the corresponding stops of the first series, the stops of the second series determining the ranges, and the stops of the first series determining the points in said ranges at which the carriage is to be stopped.

6. In a typewriting machine, the combination with a carriage, of tabulating means including slidable stop bars having racks thereon, a plurality of dial members rotatably mounted at the front of the machine, said dial members having figures each of said stops along the path of travel of said carriage, and means for severally positioning said stops along said path of travel, said positioning means including devices located atthe front of the machine by means of which said positioning means can be actuated.

8. In a typewriting machine, the combination with a traveling carriage, of tabulating mechanism including stops slidable transversely of the machine and mounted on the frame at the rear thereof, means for severally positioning said stops, a second series of stops mounted in a frame connected to travel with said carriage, each stop of said second series being supported so that it can be positioned to engage the corresponding stop of the first set but being held normally retracted, and key-actuated means to project a selected stop of the second series into position to engage the corresponding stop of the first series during the travel of the carriage, and thereby position said carriage as desired.

9. In a typewriting machine, the combination with a traveling carriage, of a series of stops vertically offset with respect to each other and supported so as to permit adjust ment along the path of carriage movement, means for adjusting said stops along said path of movement, a second series of stops mounted to move with said carriage and placed so that each of them lies in horizontal alinement with a stop of the first series, means for holding the stops of said second series in retracted position to prevent engagement thereof with stops of the first series, and means to selectively project stops of said second series and thereby position said carriage by engagement of the pro j ected stop with the corresponding stop of the first series.

10. In a typewriting machine, the combination with a traveling carriage, of a series of stops vertically displaced with respect to each other and mounted on the frame at the rear of the machine, a second series of stops slidably supported in a frame connected to travel with said carriage, each stop of said second series being in horizontal alinement with a stop of the first series, spring means for pressing the stops of the second series toward the front of the machine and thereby preventing engagement between stops of the two series, means for operatively positioning stops of the second series including a bell crank for each stop,

and a pivoted plate co-extensive with the writing range of said carriage interposed Gople: or this patent may be obtained for five cents each, by addressing the between each of said bell cranks and the corresponding stop, therebymaintaining operative connection between said bell crank and the corresponding stop throughout the travel of the carriage.

11. In a typewriting machine, the combination with a traveling carriage, of denominational stops adjustable transversely of the machine, means to position said de nominational stops in adjusted position, column stops mounted to move with the carriage, means for holding said column stops normally in retracted position to prevent engagement thereof with the denominational stops, said denominational stops and said column stops being so supported that a column stop when projected can engage only the corresponding denominational stop, andmeans to selectively project said column stops into position to engage the denominational stops, and thereby determine the positions at which the carriage will be stopped.

12. In a .typewriting machine, the combination with a traveling carriage, of a column-selecting device including a pluf rality of rotatable heads mounted at the front of the machine, each of said heads having associated therewith a dial having figures thereon conforming to the figures on the space scale of said machine, and an indicator for said dial, a plurality of stop bars slidably mounted ingroovesin a plate supported on the frame, connections whereby each of said stop bars will be actuated by means of the corresponding rotatable head, said connections including a rack on each of said stop bars anda pinion meshing therewith, a plurality of spring-retracted pins mounted on said carriage in alinement with said grooves, and means for selectively projecting said pins into the corresponding grooves and thereby causing themovement of the carriage to be checked by engagement of a projected pin with the corresponding stop bar.
